SL boot in 32 bit mode

Recommended Posts

hello, im trying to boot my 10.6.6 SL in 32 bit mode, but can't get it to work.

Im using Chameleon, what i've tried so far:


- pressing tab on Chameleon boot screen, selected SL, wrote "arch=i386" in the prompt.

- modified com.apple.Boot.plist in /Extra/ and /Library/Preferences/SystemConfiguration/ and it looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs$
<plist version="1.0">
       <key>Kernel Flags</key>
       <string>arch=i386 legacy</string>
       <key>Legacy Logo</key>


none of above works :)


To check what mode im currently in, i launch task monitor and check Type column in core processes list , its always "Intel (64-bit)"


and thoughts how to get 32 bit mode?


Im using 10.6.6

You can check in System Profiler under 'Software' whether you're running in 32- or 64-bit kernel and drivers mode:


Kernel Flags

arch=i386 legacy

That will not work.


It's -legacy. But I think this flag only works with the old Voodoo Kernel.


For more information about the -legacy flag read the Voodoo Kernel manual:
